Windows software developers denote x86 stands for 32-bit program and x64 stands 64-bit programs. The 64-bit version of the program is usually denoted by suffixing 64 or x64 with the filename — e.g., PlainTextClipbpard.exe vs. PlainTextClipbpard.exe. In some cases, the bitness notation may be missing, and you may be wondering if the executable is 32-bit or 64-bit.
To check if your current running program is 32-bit or 64-bit;
- Open Task Manager and select the Details tab in Windows10+
- Right-click on the column header and click Select columns. The column header is the row that has the caption for each column, such as Image Name, PID, Status etc.
- Enable the Platform checkbox and click OK. It will indicate if programs is 32-bit or 64-bit.
- Also recommend click command line to get path/location on disk to the file running exe.
To determine and individual file or dll use sigcheck from the command line;
sigcheck c:\windows\system32\notepad.exe
returns
